ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 652,209, dated June 19,1900.

Application filed April 2 6, 1 89 9.

To all whom. it may concern:

Be it known that I, JOHN SANFORD HAR- GER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful ImprovementsinAcetylene=Gas Machines, which are fully set forth in the followingspecification, reference being had to the accompanying drawings, forminga part hereof, and in which- Figure 1 shows my said new acetylene-gasmachine in plan View, in part fragmentary, and having a part of the topof the waterchamber broken away to expose its floor and the cover anditsyoke or cover-holder of the generator removed. Fig. 2 shows my saiddevice'in side elevation, partly fragmentary and partly in section, toshow interior construction. Fig. 3 shows the holder or cubical box whichholds both gas and water in front elevation without the gas-generator,with various Walls broken-away to show the interior construction. Fig. 4shows a plan View of a carbid-bucket, and Fig. 5 shows the same insectional elevation on the plane w w of Fig. 4, both on a scale largerthan that of Fig. 1. Fig. 6 shows a plan view of the three-way gatedconnection between the holder and gasgenerator in open position, theposition indicated in broken lines showing a closed position. Fig. 7shows most of Fig. 6 in side elevation as seen from the right-hand sideof Fig. 6. Fig. 8 shows a horizontal section of the gate shown in Fig.6, taken through the axial lines of its pipes. Fig. 9 shows the closingmechanism or cover holder of the generator. Fig. 10 shows the drip-panin central vertical section.

Like letters and numerals of reference denote like parts.

The object of my invention is to produce an acetylene-gas machine whichshall be easy of management and economical and safe in its operation. Toattain. said desirable end, I construct my said new machine insubstantially the following manner, namely:

I make a cubical holder (0 of three suitable dimensions, Figs. 1 and 2showing a portion of the rearwardly-extended dimension of said Saidholder is divided horizontally and centrally into two gas-tight SerialNo. 714,495. (No model.)

compartments a a by means of a .fioor or diaphragm a. Near the lower andthe central floors are holes a a through the front wall a of saidholder. the rear wall of a well Z7, which is in front of said holder andflush with one side of it. Slightly-above said hole a enters the lower Iend of a connecting pipe a into the gas chamber and rises to near thetop of the chamher a called a water-chamber, which it enters, as shown.The well I) is a rectangular open cistern of about the same depth as theheight of the holder at, to the side of which and in front of the holderat is another open-top cistern 0, attached to the holder a and separatedfrom said well by a wall a having its front wall in the same plane inwhich is the front wall of the well 6 and of which its farther side wallis in a plane cor- 7o responding to that wall of the holder a. Thebottom a of said cistern is about in the same plane as that of thediaphragm a, and about midway between said floor and the groundfloor ofthe holder at is a horizontal floor 0', 7

pipe is placed at such a depth below the floor a as to be alternately ineither the gas or water space of the gas-chamber, as will appearhereinafter.

The generator d is provided with superimposed carbid-buckets Z which aredivided into cells, as here shown, from l 2 3 o to 15, having a centraldischarge-pipe,---wi-th.,notch 16 and top notches n between the cells 2and 3 and similarly between all other of There is a three-way 5 saidcells, as shown. gate 10 in the pipe d, provided with a lever Z having avertical handle close to the central side of a horizontal bar '11. Agas-pipe c from the gas-chamber a ascends out of the well a shortdistance and then becomes hori- I00 zontal and provided with a gate J,from which it descends, as pipe 6, below the plane of the Said frontwall also forms 55 A gasometer or 80 near the top of the roof-dome c andthe other branch of said T descends through a water seal to near thefloor of the tank A roofdome c has a gas-pipe h descending; from nearits top through the floor a" and passes to near the bottom of the tank 0where its open end is also in a water seal, and has a T just below thefloor d from which a horizontal pipe h passes into the well I) and thenrises, as pipe 72, which supplies the burner-pipes. Said hell 0 also hasa central dome c, which descends to the plane of the bottom of the bell,and about eight or nine inches from its lower end are blow-holes c andin said dome is a gas-pipej, which passes through the floor a and endsin a T, one end of which is open at 7' and the other end forms ahorizontal pipe j, which passes into the well I) and then ascends, aspipe 7t, which near the top of the well receives an inlet-pipe 0' fromthe top of the water-chamber a, said pipes 0 and 76 forming blow=off orsafety pipes. A bracket Z, provided with pins Z, is fastened to the bell0 so as to be on one edge of a pulley f, attached to the gate f, andaround said pulley is passed a cord at, whereof the ends are fastened tosaid pins Z, whereby as the tank 0 rises and lowers said gate turns, andthus throttles the flow of gas.

The top carbid-cells are covered by a drippan 9, having a bottom 19 andrim p fitting closely within the tank d, and. on said rim is a sleeve 10which slides over the end of the feed-pipe d, which passes through theboss g on the tank (1, into which it is threaded, and around the end ofsaid pipe is an annular space q in said boss to receive the sleeve 13which thus prevents the passage of water outside of the drip-pan insteadof through the hole 1 in the pan-bottom and which said hole is directlyover cell 1. A handle sis provided for lifting said pan, and an open rim7' prevents the water from the pipe (1 overflowing the said pan.

Toput the machine in operation, the carbidcells 1 to 15 are charged eachwith a given Weight of carbid and the tank and pipe 01 closed with thegate wand lid t. Water is then poured into the well until it rises abovethe level of the floor a, which thereby also fills the gas chamber awith water. The bell c is sealed with water and the chamber 0 providedwith its water seal through the funnel m. \Vater is. then allowed toflow through the gate into carbid-cell l. The

gas thus generated flows over the inflowing water through the pipe 61and accumulates over the water in the gas-chamber a thereby depressingthe water in said chamber by causing it to flow out through the hole aand rise to a head 9 in the Well I), from which it flows through thehole a into the water-chamber a where the water is stored and fromwhence it flows as it is needed. When said gas-pressure ceases or thegas is exhausted sufficiently from the gas chamber, the Water returns tothe gas-chamber until it again flows into the generator and saturatesand fills another carbid-cell, whereby the gas-pressure is renewed andthe water again lowered below the pipe 02, and so on continuously. Thegas escapes from the gas-chamber through the pipe e, gate f, and pipes ee 8 into the gasometer c and from it through the pipes 71.72171 to theburners connected to the pipe h. Un der the varying gas-pressure thegasometer rises and falls, and thus by means of said cord 'n, turns thegate f, which thereby throttles the flow of gas and thereby keeps apractically-uniform pressure on the service-pipes. If, accidentally, thegas-pressure should continue to lower the water-level in the gas-chamberuntil it falls below the entrance of the pipe a, the gas will thenescape through the pipe a into the top of the Water-chamber a, which isnow also nearly full of water, from which the gas will escape throughthe pipe 0 into the blow-ofi or safety pipe 70, and thus prevent alldanger of explosion. In like manner if the gasometer should stick andgas continue to flow the gas would lower the water-level g within thebell 0 until the gas escaped through the blow-off holes 0 of the dome cand thence escaped down the pipe j into the horizontal pipe j, where atf it would discharge into the tank 0 at one end and into the pipe k atits other end, and in case that pipe should fail the water in the tank 0would be depressed and overflow the funnel m. In the meantime and beforesuch final result the gas might also escape through the water-sealedends 6 h and rise above the water in the drip-chamber c and therebycause its water to overflow the funnel m and release the pressure beforethe said last preceding condition occurred.

The eyes or lugs u of the generator receive the ends of the yoke c,which is provided with a screw '0 whose end depresses the lid tgas-tight on the generator. The operatinglever 22 of said screw is closeto the vertical handle Z of the lever P, which opens the three-way gatew,when the pipe (1 passes the gas. The position of said parts 4; and Zis for the special purpose of necessitating the removal of said handle Zwhich when done closes the gate 10 to the escape of gas from thegas-holder and thereby prevents accidents. When this machine is to beset in operation, water is poured into the well 19 until the gas-chamber01. is at least entirely full of.

water. The air escapes through the pipe e and gate f, which is set forthat purpose and afterward rearranged to its normal position.

-What I claim is 1. The combination with connected, topnotched andsuccessively-acting carbid-cells and a gated gas and water conveyingpipe, of a water-filled gas-chamber below a waterchamber and a well,exterior to and connect- ICC .notched and successively-actingcarbid-cells and a generator with a single pipe opening therein, of adrip-pan with a hole in its bottom and a sleeve to its rim to surroundthe end of said pipe, substantially as specified.

4. The combination with a water-charged gas-chamber and a superimposedWater-chamber and a well to connect said chambers, of a water-sealedgasometer, a pipe, or pipes, connecting said gas-chamber and gasometer,a 25 rotary gate in said pipe, or pipes, and reciprocating mechanismwith means to connect the same to said rotatable gate, substantially asspecified.

5. The combination Witha gas-generatora 3o gas-chamber and asuperimposed water-chamber and a Well to connect said gas and Waterchamber, of a gasometer and a drip-chamber and gas-receiving andgas-discharging pipes with water-sealed parts in said drip-chamber, 35substantially as specified.

6. The combination with a gas-generator, a gas=chamber,and asuperimposed water-chain ber, and a well with water connections to saidchambers, a floating gas-tank and gas-pipes 0 to and from said gas-tank,of a blow-off pipe and a yielding water seal to said gas-pipes,substantially as specified.
